CONSTRUCTION
The resistor is constructed on top of a high-grade
ceramic body. Internal metal electrodes are added at
each end and connected by a resistive glaze. The
resistive glaze is covered by a lead-free glass. The
composition of the glaze is adjusted to give the
approximately required resistance value. The whole
element is covered by a protective overcoat. The
top of overcoat is marked with the resistance value.
Finally, the two external terminations (Ni/matte tin)
are added, as shown in Fig.4.

RATED VOLTAGE
The DC or AC (rms) continuous working voltage
corresponding to the rated power is determined by
the following formula:
V =
R) X (P
Where
V = Continuous rated DC or AC (rms) working voltage (V)
P = Rated power (W)
R = Resistance value (Ω)
